摘　　要：以河西地区的石羊河流域为例,对影响绿洲农业生态系统的人类经营水平,农业生态气候适宜性,土壤肥力,水资源条件以及不同地段绿洲的自然生产能力,水经济效益,生产效率进行了模拟分析;依据我国西北内陆流域自然生态条件的内部差异和上述分析结果,论述了干旱地区灌溉农业开发和绿洲建设问题。研究表明,干旱内陆流域中游的绿洲一般是高质量、高效益的农业生产系统,而下游末段的绿洲效益最低。With Shiyang Watershed in the West Bank of the Yellow River as an example,thispaper analyses the effects of human management level,agro-climatic suitability,soil fer-tility,water resources,natural productivity of oasis in various sections,economic returnsof water use,and productive efficiency upon oasis agro-ecological system.Based on in-ternal difference of natural ecological conditions of inland watershed and the above ana-lysis,this paper deals with the development of integrated agriculture and the oasiscontruction in the arid area.The results showed that oasis in the middle part of the airdinland watershed is the high quality agricultural production system while the benefits ofoasis in the end of the lower reaches are the lowest.
